When cut in 3mm acrylic, the smallest 8mm link will bend to 90 degrees but is fragile if mistreated. The middle size 14mm link will bend further, but may not reach 180 degrees if the sample is cold or excessive bending is performed quickly. The tallest sample (28mm) can be bent comfortably to 180 degrees, but is noticeably less stiff than the other two.

Having an understanding of how these lattice hinges work will allow you to create better products with less failures.
